Obesity and Depression Independently Increase Health Costs

Obesity and depression both dramatically increase health care costs, but they mainly act separately, according to a study published in the November 2011 Journal of General Internal Medicine by Group Health Research Institute scientists. Gregory Simon, MD, MPH, a Group Health psychiatrist and Group Health Research Institute senior investigator, led the research.

"Previous research shows that both depression and obesity are associated with higher health care costs," he said. "But depression and obesity often occur together, so it was important to know if the relationship between obesity and cost is really due to depression -- or vice versa."
